Mission statement - The 2011 Draconids Multi-Instrument Aircraft Campaign is an international campaign to study the exceptional 2011 October 8 Draconid meteor outburst from the air and ground.

Calculate the rate of 2011 Draconid meteors at your site

What is the best location for viewing the 2011 Draconid shower? You can calculate the answer yourself with the handy FLUXTIMATOR Java Applet below (courtesy of Peter Jenniskens and David Nugent). Choose the shower, the date, and a nearby location. Check your timezone carefully. The applet then calculates the expected shower rate.

Tip: The applet does not show the early evening hours. You can bring this part of the flux curve in view by choosing "other" and changing the timezone setting. Keep in mind that this, of course, will shift the meaning of the time axis at the bottom of the graph.

The applet also allows you to see the difference between staying downtown or moving out into the countryside to a dark and clear location. All rates were calculated by taking into account Daylight Savings Time (DST) and the Moon light, which is a significant disturbance during the Draconids.

Disclaimer: Make sure that Java is enabled. The duration, peak activity and time of the peaks are based on recent numerical models and past Draconid shower observations, and may be in error by hours in peak time, and an unknown amount in peak rate. Rates are based on the model by Vaubaillon, while results from others differ significantly.
